CPU clocking

Posted 31 December 2011 - 12:44 AM

Alright so my CPU is set to run at 1.75 ghz when I have a Dell duo core 2.5 ghz CPU. (sorry if that seems redundant) So what Im attempting to do it go into my Bios and change the clock speed. I have a Dell A11 bios on a Dell XPS m1730. I looked all over Dells site and did not find anything. Also The bios is up to date for the machine.

I am running Windows vista as my laptop does not support Windows 7 due to drivers. I had a friend tell me to unlock the Bios through CMD??? He is looking for the command as he works for geek squad.

More or less what Im asking for is if anyone knows how to change the clock speed.

Mobile CPUs tend to have a more dynamic clock speed than their PC counterparts. They'll down-clock when the CPU is mostly idle to save power. Have you tried looking through the Power Options control panel to see if this is happening? It's also possible that you have software tailored to your laptop made by it's manufacturer.

Then check your BIOS by:
Rebooting your computer by turning it off then back on.
WATCH for a message that says something like "Press F1 to change system settings"
The key differs from computer to computer (Del, Tab, F12 etc...)
Once you are in BIOS you can look at your settings and see how you Hardware is configured.
Depending on the model of your computer you MIGHT be able to change your CPU speed, but if it's a cheep computer like mine you won't have the option of changing the speed.

More than likely it might have a setting for power management that you can turn off to get the CPU to run at full speed all the time.

It's a Dell. Replacing the CPU will cause the system to no longer boot. Dell is incredibly limited about what they will allow to be changed on the systems they build and this is the reason that a lot of people refuse to buy Dell computers. Even if you do manage to find a CPU that will work together with the motherboard on that computer, you will need to re-install a new operating system as Dell makes it so that the operating system will only work with the hardware that it was originally installed on. If you ever want to upgrade a Dell computer, you're better off buying a new computer. As far as overclocking it, I can't offer any advice on that as I am not familiar with that particular BIOS for Dell computers.

Only if it happens while you're using it. If it is planned, then it is awesome. I can think of tons of computers that I have wanted to set on fire over the years. Including at least 30 computers at work right now.
